Help! Check Engine light/bogging after 4k rpm

The SAFC is working, but I noticed my check engine light went on and the car seems a whole lot more sluggish. Also, after I get to about 4,000 RPMS my car feels like it got hit in the stomach and loses it's push and feels like it's bogging. Also the car doesn't sound like it used to. What's the prob? Any ideas? Is there some safc settings I should be putting in or something?

EDIT: used the field harness if that helps.

try take the afc off and run it for a while, if eveyrthing went back to normal, then its your settings. From the sound of it, you prob lean out too much at around 4k.....

Check all of the hoses associated with the turbo and intercooler system. Sounds like one blew off and you are not getting into boost because the pressure is escaping, just tighten it back up and see what happens.

Check to make sure the "Sensor Type" is set the Karman.

And "Car Select" is set to 4.

yepo, it was the karman sensor that fixed the rpm problem. I already thought it was set to karman, but that's ok. The Service engine soon light is still on though. any ideas bout that one?
